You're right... I have a hard time having casual sex on camera. After all my sex life off camera is nowhere as large as it is on camera. I've been with one person prior to my current boyfriend and we hardly had much of a intercourse relationship. So who I'm with now is my only standing partner. Prior to, I never dated with others nor became close to other people in a near sexual manner. I know it's odd but if I'm not glued down in a relationship with expectations of long term than I don't want to be bothered and rather living my own life on my own.
Working on camera keeps guys from trying to hang out with me as relating buddies that I'm not interested in. It keeps guys from saying stuff that I'd consider making myself feel uncomfortable on a personal level. It keeps guys from asking me to do other sexual acts other than whats agreed upon. It keeps guys from constantly on my ass physically trying to get a feel because they cant control themselves. I get irritated by touchy feely people, grrr... and so many other things I can list. That's why I love camera work. We can do it, get wild and nasty and have fun at the sametime without anyone crossing eachothers boundaries.
